A distributed information retrieval system with resource-selection and result-set merging capability was used to search subsets of the GOV2 document corpus for the 2008 TREC Million Query Track. The GOV2 collection was partitioned into host-name subcollections and distributed to multiple remote machines. The Multisearch demonstrations, application restricted each search to a fraction of the available sum-collections that was pre-determined by a resource-selection algorithm. Experiment results...

The effects of heat transfer on engineering applicationsis a fundamental aspect in the design of power and propulsive systems. The heat exchange between fluid and solid parts may reduce the efficiency of the system in situations where temperature peaks and gradients become important. This is the case of gas turbines, combustion engines or cooling of turbine blades. However, this interaction is difficult to model numerically not only due to the different time scales governing each individual...

One of the major sources of uncertainty in model estimates of the global sea-salt aerosol distribution is the emission parameterization. We evaluate a new sea-salt aerosol life cycle module coupled to the online multi-scale chemical transport model NMMB/BSC-CTM. We compare 5 year global simulations using five state-of-the-art sea-salt open-ocean emission schemes with monthly averaged coarse aerosol optical depth (AOD) from selected AERONET sun photometers, surface concentration measurements...

Ejecta fragments from cratering on Tethys coorbital (Trojan) moons result in impacts onto Tethys that are unusual in terms of size distribution, impact velocity, and location. We find that crater ejecta escaping from L4 (Telesto) or L5 (Calypso) can explain two major features of Tethys' geologic record: the lens-shaped albedo feature on the far side and the overall surplus of 1-20 km diameter impact craters. Further analysis of these connections can help tie together our understanding of...

This paper proposes a definition for VPC, an extended C programming language for vector-parallel applications. VPC is a superset of the conventional C language that contains extensions for vector and parallel machines. New constructs and their semantics are presented, along with some discussion about potential problems that arise when extending C into the parallel domain. The reader is assumed to be familiar with the C programming language--this paper only describes those aspects of VPC that...

After studying two specific implementations of virtual ring, Virtual Ring on Embedded Tree and Virtual Ring of Traveling Salesman Tour, we propose a novel ring-based survivable architecture for group communication, called the Multi-Ring Virtual Ring (MVR). MVR is capable of tolerating one link or one node failure and is easy to...

Parallel computing is an enabling technology for many areas of science and engineering. Parallel computing is also our best investment to continue achieving performance gains as the limits of semiconductor technology are approached. Whereas the design of parallel computers is reasonably well-understood, the programming of these machines remains in its infancy. As a consequence, programming parallel computers is substantially more difficult than programming conventional uniprocessors. In fact,...

The purpose of the research was to study robust iterative methods for solving spare (block tridiagonal) nonsymmetric linear systems in a parallel computing environment. A new method was developed which uses block-row symmetric successive overrelaxation (SSOR) with conjugate gradient (CG) acceleration. The method is robust, with convergence assured even for poorly conditioned systems, and the method is easily implemented in a parallel environment. The method transforms a nonsymmetric system with...

The training problem for feedforward neural networks is nonlinear parameter estimation that can be solved by a variety of optimization techniques. Much of the literature of neural networks has focused on variants of gradient descent. The training of neural networks using such techniques is known to be a slow process with more sophisticated techniques not always performing significantly better. It is shown that feedforward neural networks can have ill-conditioned Hessians and that this...
